Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

This discussion contains forward-looking statements that involve risks and uncertainties. The forward-looking statements are not historical facts, but rather are based on current expectations, estimates, assumptions and projections about the midstream industry and our business and financial results. Our actual results could differ materially from the results contemplated by these forward-looking statements due to a number of factors, including those discussed in the sections entitled "Forward-Looking Statements" and "Risk Factors."

OVERVIEW

Our Business

We are an owner, operator, and developer of an integrated portfolio of natural gas midstream assets. We provide multiple, integrated natural gas services to customers through our Pipeline segment, which includes interstate pipelines, intrastate pipelines, storage systems, and gathering lateral pipelines, and through our Gathering segment. We also own joint venture interests in equity method investees which own and operate interstate pipelines that connect to our wholly owned assets. On December 31, 2024, we closed on the Midwest Pipeline Acquisition of three FERC-regulated natural gas transmission pipelines. See Note 16, "Acquisitions" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

Our core assets strategically connect key demand centers in the Midwestern U.S., Eastern Canada and Northeastern U.S. regions to the premium production areas of the Marcellus/Utica natural gas formation in the Appalachian Basin and connect key demand centers and LNG export terminals in the Gulf Coast region to premium production areas of the Haynesville natural gas formation.

We have an established history of stable, long-term growth with contractual cash flows from customers that include natural gas producers, local distribution companies, electric power generators, industrials, and national marketers.

Our Strategy

See discussion of our strategy under Part I, Items 1. and 2. "Business and Properties—Our Strategy" of this Form 10-K.

Pipeline

The Pipeline segment consists of our interstate pipelines, intrastate pipelines, storage systems, gathering lateral pipelines including related treatment plants and compression and surface facilities. This segment also includes our equity method investments. During the three months ended March 31, 2023, we completed the conversion of the Michigan System from gathering to dry gas transmission service and began providing services under a new long-term dry gas transmission contract. For the years ended December 31, 2024 and 2023, the Michigan System financial results are presented in the Pipeline segment. The activity for the year ended December 31, 2022 was for gathering services and therefore was not revised from presentation in the Gathering segment.

Pipeline results and outlook are discussed below:

[[/GREPCENT_TABLE]]

Operating revenues increased $66 million for the year ended December 31, 2024 primarily due to new LEAP long-term firm service revenue contracts of $55 million, higher long-term contracting rates and volumes at the Washington 10 Storage Complex of $9 million and higher volumes at Stonewall of $9 million, partially offset by lower volumes at Bluestone of $8 million. Operating revenues increased $38 million for the year ended December 31, 2023 primarily due to higher long-term and short-term storage contracting rates at the Washington 10 Storage Complex of $18 million, new transmission service contracts at the Michigan System of $16 million, and new LEAP long-term firm service revenue contracts of $10 million, partially offset by lower volumes at Bluestone of $2 million.

Operation and maintenance expense increased $13 million for the year ended December 31, 2024 primarily due to higher production-related operating expenses from the expansion of LEAP and acquisition related costs for the Midwest Pipeline Acquisition. Operation and maintenance expense increased $1 million for the year ended December 31, 2023 primarily due to new transmission service contracts at the Michigan System, partially offset by increased capitalized labor and overhead.

Depreciation and amortization expense increased $5 million for the year ended December 31, 2024 primarily due to new LEAP assets placed into service. Depreciation and amortization expense increased $6 million for the year ended December 31, 2023 primarily due to new transmission service assets at the Michigan System and new LEAP assets placed into service.

Taxes other than income increased $7 million for the year ended December 31, 2024 primarily due to LEAP assets placed into service.

Asset (gains) losses and impairments, net decreased $4 million for the year ended December 31, 2024 due to a one-time gain realized from an insurance settlement that occurred in the prior year.

43

Interest expense decreased $8 million for the year ended December 31, 2024 primarily due to lower outstanding borrowings under the Revolving Credit Facility and the repayment of the Term Loan Facility during 2024, partially offset by lower capitalized interest driven by lower construction in progress during 2024 and higher interest related to the Bridge Facility and 2034 Notes. Interest expense decreased $2 million for the year ended December 31, 2023 primarily due to higher capitalized interest on higher construction in progress during 2023, partially offset by higher borrowings and rates under the Revolving Credit Facility, higher interest rates on the Term Loan Facility, and a full year of interest expense related to our 2032 Notes.

Earnings from equity method investees decreased $15 million for the year ended December 31, 2024 primarily due to higher interest expense from new senior unsecured notes at Millennium and a full year of interest expense from senior unsecured notes at NEXUS. Earnings from equity method investees increased $27 million for the year ended December 31, 2023 primarily due to higher earnings from Millennium of $19 million from our higher ownership percentage and a goodwill impairment at Generation of $7 million in 2022. Additionally, NEXUS had increased contract rates and additional customers offset by higher interest expense from new senior unsecured notes. On October 7, 2022, DT Midstream closed on the $552 million purchase of an additional 26.25% ownership interest in Millennium from National Grid. See Note 1, "Description of the Business and Basis of Presentation" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

Loss from financing activities increased $3 million for the year ended December 31, 2024 primarily due to the repayment of our remaining Term Loan Facility that occurred during the current year. Loss from financing activities decreased $6 million for the year ended December 31, 2023 due to the partial repayment of our Term Loan Facility that occurred during the three months ended June 30, 2022. See Note 10, "Debt" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K for further details.

Income tax expense increased $32 million for the year ended December 31, 2024 primarily due to higher income before income taxes and deferred tax remeasurement adjustments for changes in state tax rates and apportionment factors due to the Midwest Pipeline Acquisition and enacted state legislation. Income tax expense increased $13 million for the year ended December 31, 2023 due to higher income before income taxes in 2023. Income tax expense for the years ended December 31, 2023 and 2022 include the impacts of net tax benefits related to state tax rate changes. See Note 7, "Income Taxes" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K for further details.

Pipeline Outlook

We believe our long-term agreements with customers and the location and connectivity of our pipeline assets position the business for future growth. We will continue to pursue economically attractive expansion opportunities that leverage our current asset footprint and strategic relationships. These growth opportunities include DTM Interstate Transportation assets, further expansion at LEAP and Stonewall, new contracts at the Washington 10 Storage Complex and additional growth related to our equity method investments.

44

Gathering

The Gathering segment includes gathering systems, related treatment plants and compression and surface facilities. Gathering results and outlook are discussed below:

[[/GREPCENT_TABLE]]

Operating revenues decreased $7 million for the year ended December 31, 2024 primarily due to lower volumes and recovery of production-related operating expenses on Blue Union Gathering of $19 million and lower Susquehanna Gathering volumes of $16 million, partially offset by a full year of operations at Ohio Utica Gathering of $18 million and higher Appalachia Gathering volumes of $12 million. Operating revenues decreased $36 million for the year ended December 31, 2023 primarily due to lower Blue Union Gathering revenues of $50 million, lower Michigan System gathering services of $6 million, and lower Susquehanna Gathering volumes of $3 million, partially offset by higher Appalachia Gathering volumes of $21 million driven primarily by new contracts resulting from the expansion in 2023. Lower Blue Union Gathering revenues were driven primarily by lower deficiency fees of $23 million, lower recovery of production-related operating expenses of $12 million, lower rates of $9 million and lower production volumes of $5 million.

Operation and maintenance expense decreased $14 million for the year ended December 31, 2024 primarily due to lower planned maintenance and production-related operating expenses on Blue Union Gathering of $18 million, partially offset by a full year of operations at Ohio Utica Gathering. Operation and maintenance expense decreased $23 million for the year ended December 31, 2023 primarily due to lower Blue Union Gathering expenses of $14 million driven by lower production-related operating expenses, a reduction in Appalachia Gathering environmental contingent liabilities of $6 million, and increased capitalized labor and overhead of $3 million.

Depreciation and amortization expense increased $22 million for the year ended December 31, 2024 primarily due to assets placed into service at Ohio Utica Gathering, Blue Union Gathering, and Appalachia Gathering. Depreciation and amortization expense increased $6 million for the year ended December 31, 2023 primarily due to new Blue Union Gathering and Appalachia Gathering assets placed into service.

Taxes other than income increased $4 million for the year ended December 31, 2024 primarily due to assets placed into service at Blue Union Gathering.

Asset (gains) losses and impairments, net decreased $17 million for the year ended December 31, 2023 due to the 2022 one-time gain on sale of certain assets in the Utica Shale region. See Note 2, "Significant Accounting Policies" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

Interest expense increased $11 million for the year ended December 31, 2024 primarily due to lower capitalized interest driven by lower construction in progress during 2024 and higher interest related to the Bridge Facility and 2034 Notes issued in 2024. This increase was partially offset by lower outstanding borrowings under the Revolving Credit Facility and the repayment of the Term Loan Facility during 2024. Interest expense increased $15 million for the year ended December 31, 2023 primarily due to higher borrowings and interest rates under the Revolving Credit Facility, higher interest rates on the Term Loan Facility, and a full year of interest expense related to our 2032 Notes, partially offset by higher capitalized interest due to higher construction in progress during 2023.

45

Loss from financing activities increased $2 million for the year ended December 31, 2024 primarily due to the repayment of our remaining Term Loan Facility that occurred during the current year. Loss from financing activities decreased $7 million for the year ended December 31, 2023 due to the partial repayment of our Term Loan Facility that occurred during the three months ended June 30, 2022. See Note 10, "Debt" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

Income tax expense increased $1 million for the year ended December 31, 2024 primarily due to deferred tax remeasurement adjustments for changes in state tax rates and apportionment factors due to the Midwest Pipeline Acquisition and enacted state legislation, partially offset by lower income before income taxes. Income tax expense decreased $9 million for the year ended December 31, 2023 primarily due to lower income before income taxes in 2023. Income tax expense for the years ended December 31, 2023 and 2022 include the impacts of net tax benefits related to state tax rate changes. See Note 7, "Income Taxes" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

Gathering Outlook

We believe our long-term agreements with producers and the quality of the natural gas reserves in the Marcellus/Utica and Haynesville formations position the business for future growth. We will continue to pursue economically attractive expansion opportunities that leverage our current asset footprint and strategic relationships. These growth opportunities include further expansions at Blue Union Gathering, Appalachia Gathering, Ohio Utica Gathering, Tioga Gathering and Clean Fuels Gathering.

ENVIRONMENTAL MATTERS

We are subject to extensive U.S. federal, state, and local environmental regulations. Additional compliance costs may result as the effects of various substances on the environment are studied and governmental regulations are developed and implemented. Actual costs to comply with such regulation could vary substantially from our expectations. Pending or future legislation or regulation could have a material impact on our operations and financial position. Potential impacts include unplanned expenditures for environmental equipment, such as pollution control equipment, financing costs related to additional capital expenditures, and the replacement costs of aging pipelines and other facilities.

For further discussion of environmental matters, see Part I, Items 1. and 2. "Business and Properties — Regulatory Environment — Environmental and Occupational Health and Safety Regulations" and Note 12, "Commitments and Contingencies" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

CLIMATE CHANGE

We believe we have an opportunity to address climate change and have made strategically aligned environmental investment decisions a priority. Our Board of Directors includes a committee focused on environmental, social and governance initiatives, and our strategy will focus on targeted growth from carbon-reducing technologies associated with our current platforms. We have announced our intent to employ carbon-reducing technologies as part of our goal of being leading environmental stewards in the midstream industry, and we are executing on a plan to achieve net zero carbon emissions by 2050. We established our baseline Scope 1 carbon emissions in 2021 and are targeting a 30% reduction from this baseline by 2030.

In 2024, we completed the Clean Fuels Acquisition and advanced our carbon capture and sequestration project in Louisiana through completion of the Class V test well. The carbon capture and sequestration Class VI permit application was transferred to the Louisiana Department of Energy and Natural Resources in February 2024, and we are awaiting the completion of their review.

In future years, we plan to continue to make progress on opportunities for energy transition advancements leveraging our existing assets, competencies and partnerships. These opportunities include the following:

•Our efforts to advance our Louisiana carbon capture project, as well as other potential carbon capture projects across our geographic regions;

•Our Clean Fuels Gathering project to capture fugitive methane emissions; and

•Our strategic joint development agreement with Mitsubishi Power Americas, Inc. to advance hydrogen development projects across the United States.

46

Capital project investments have been contemplated in our forecasted capital expenditures discussed in the Capital Investments section below. DT Midstream published our third annual Corporate Sustainability Report in 2024. The information in our Corporate Sustainability Report is not incorporated by reference into this Form 10-K.

For discussion of various risks including transitional risks associated with climate change related laws and regulations, reputational risks of climate change, and the physical risks of climate change, see Part I, Item 1A. "Risk Factors—Risks Relating to Our Business—Regulatory Risks—Risks related to climate change could materially adversely affect our business, financial condition, results of operations, cash flow, access to and cost of capital or insurance, reputation, and business strategies." of this Form 10-K. For discussion of recent climate change related laws and regulations, see Part I, Items 1. and 2. "Business and Properties—Regulatory Environment—Environmental and Occupational Health and Safety Regulations—Climate Change" of this Form 10-K.

CAPITAL RESOURCES AND LIQUIDITY

Cash Requirements

Our principal liquidity requirements are to finance our operations, fund capital expenditures, satisfy our indebtedness obligations, and pay approved dividends. We believe we will have sufficient internal and external capital resources to fund anticipated capital and operating requirements.

[[GREPCENT_TABLE]]
[["","","","Year Ended December 31,"],["","","","","","2024","","2023","","2022"],["","","","(millions)"],["Cash and Cash Equivalents at Beginning of Period","","","","","$","56","","","$","61","","","$","132"],["Net cash and cash equivalents from operating activities","","","","","763","","","798","","","725"],["Net cash and cash equivalents used for investing activities","","","","","(1,081)","","","(351)","","","(854)"],["Net cash and cash equivalents from (used for) financing activities","","","","","330","","","(452)","","","58"],["Net Increase (Decrease) in Cash and Cash Equivalents","","","","","12","","","(5)","","","(71)"],["Cash and Cash Equivalents at End of Period","","","","","$","68","","","$","56","","","$","61"]]
[[/GREPCENT_TABLE]]

For purposes of the following discussion, any increases or decreases refer to the comparison of the year ended December 31, 2024 to the year ended December 31, 2023 and the year ended December 31, 2023 to the year ended December 31, 2022.

Operating Activities

Cash flows from our operating activities can be impacted in the short term by the natural gas volumes gathered or transported through our systems under interruptible service revenue contracts, changing natural gas prices, seasonality, weather fluctuations, dividends received from equity method investees, working capital changes and the financial condition of our customers. Our preference to enter into firm service revenue contracts leads to more stable operating performance, revenues and cash flows and limits our exposure to natural gas price fluctuations.

Net cash and cash equivalents from operating activities decreased $35 million for the year ended December 31, 2024 primarily due to a decrease in working capital changes and a decrease in dividends received from equity method investees, partially offset by a decrease in cash paid for income taxes and an increase in operating income after adjustment for non-cash items including depreciation and amortization expense, stock-based compensation, and amortization of operating lease right-of-use assets.

Net cash and cash equivalents from operating activities increased $73 million for the year ended December 31, 2023 primarily due to a decrease in cash paid for taxes, net changes in working capital, an increase in operating income after adjustment for non-cash items including depreciation and amortization expense, stock-based compensation, amortization of operating lease right-of-use assets, and assets (gains) losses and impairments, and an increase in dividends received from equity method investees. These increases were partially offset by an increase in interest expense.

47

Investing Activities

Cash outflows associated with our investing activities are primarily the result of plant and equipment expenditures, acquisitions, and contributions to equity method investees. Cash inflows from our investing activities are generated from proceeds from sale or collection of Notes receivable, distributions received from equity method investees, and proceeds from asset sales.

On December 31, 2024, we closed on the Midwest Pipeline Acquisition of three FERC-regulated natural gas transmission pipelines for $1.2 billion. See Note 16, "Acquisitions" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

As a result of the sales of senior unsecured notes at our equity method investees, we received net distributions from Millennium of $416 million and NEXUS of $371 million during the years ended December 31, 2024 and 2023, respectively. See Note 1, "Description of the Business and Basis of Presentation" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

Net cash and cash equivalents used for investing activities increased $730 million for the year ended December 31, 2024 primarily due to cash consideration for the Midwest Pipeline Acquisition, partially offset by a decrease in cash used for plant and equipment expenditures and higher distributions received from equity method investees, including those noted above.

Net cash and cash equivalents used for investing activities decreased $503 million for the year ended December 31, 2023 primarily due to the acquisition of an additional 26.25% ownership interest in the Millennium from National Grid in 2022 and higher distributions received from equity method investees in 2023, including the NEXUS distribution noted above. This change was partially offset by an increase in cash used for plant and equipment expenditures for expansions on LEAP, Blue Union Gathering, Appalachia Gathering, and Ohio Utica Gathering, and a decrease in proceeds from the sale of notes receivable.

Financing Activities

In December 2024, we issued the 2034 Notes in aggregate principal amount of $650 million, and we amended the Credit Agreement to, among other things, extend the Revolving Credit Facility maturity date to 2029. In November 2024, we amended our Credit Agreement to permit the Company to incur certain customary bridge loans, including the Bridge Facility. In September 2024, we repaid the remaining indebtedness under the Term Loan Facility of $399 million. See Note 10, "Debt" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

In November 2024, we issued 4,168,750 common shares for net proceeds of approximately $406 million. DT Midstream paid cash dividends on common stock of $280 million, $263 million, and $244 million during the years ended December 31, 2024, 2023 and 2022, respectively. See Note 8, "Earnings Per Share and Dividends" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

In April 2022, we issued the 2032 Notes in aggregate principal amount of $600 million. We used the net proceeds from the sale of the 2032 Notes of $593 million to partially repay indebtedness under our Term Loan Facility.

Net cash and cash equivalents from financing activities of $330 million for the year ended December 31, 2024 increased as compared to net cash and cash equivalents used for financing activities of $452 million for the year ended December 31, 2023. The increase was primarily due to proceeds received from the issuance of common shares, proceeds received from the issuance of the 2034 Notes, and lower net repayments of borrowings under the Revolving Credit Facility, partially offset by the repayment of the Term Loan Facility and higher dividends paid on common stock.

Net cash and cash equivalents used for financing activities of $452 million for the year ended December 31, 2023 increased as compared to net cash and cash equivalents from financing activities of $58 million for the year ended December 31, 2022. The increase was primarily due to higher net repayments of borrowings under the Revolving Credit Facility, higher dividends paid on common stock, and lower proceeds from the issuance of long-term debt. The increase was partially offset by lower repayments of long-term debt.

48

Outlook

We expect to continue executing on our natural gas-centric business strategy focused on disciplined capital deployment and supported by a flexible, well capitalized balance sheet. Other than the impact of the items discussed below on our debt and equity capitalization, we are not aware of any trends, other demands, commitments, events or uncertainties that are reasonably likely to materially impact our liquidity position.

Our working capital requirements will be primarily driven by changes in accounts receivable, accounts payable and taxes payable. We continue our efforts to identify opportunities to improve cash flows through working capital initiatives and obtaining long-term firm service revenue contracts from customers.

Our sources of liquidity include cash and cash equivalents generated from operating activities and available borrowings under our Revolving Credit Facility. As of December 31, 2024, we had $16 million of letters of credit outstanding and $150 million borrowings outstanding under our Revolving Credit Facility. We had approximately $902 million of available liquidity as of December 31, 2024, consisting of cash and cash equivalents and available borrowings under our Revolving Credit Facility.

We expect to pay regular cash dividends to DT Midstream common stockholders in the future. Any payment of future dividends is subject to approval by the Board of Directors and may depend on our future earnings, cash flows, capital requirements, financial condition, and the effect a dividend payment would have on our compliance with relevant financial covenants. Over the long-term, we expect to grow our dividend with cash flow growth.

We believe we will have sufficient operating flexibility, cash resources and funding sources to maintain adequate liquidity amounts and to meet future operating cash, capital expenditure and debt servicing requirements. However, our business is capital intensive, and the inability to access adequate capital could adversely impact future earnings and cash flows.

The Credit Agreement covering the Revolving Credit Facility includes financial covenants that DT Midstream must maintain. See Note 10, "Debt" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

See also Note 12, "Commitments and Contingencies" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

Credit Ratings

Credit ratings are intended to provide banks and capital market participants with a framework for comparing the credit quality of securities and are not a recommendation to buy, sell, or hold securities. Our credit ratings affect our cost of capital and other terms of financing, as well as our ability to access the credit and commercial paper markets. We believe that the current credit ratings provide sufficient access to capital markets. However, disruptions in the banking and capital markets not specifically related to us may affect our ability to access these funding sources or cause an increase in the return required by investors. During the year ended December 31, 2024, our credit rating was upgraded to investment-grade by Fitch Ratings and our outlook was upgraded to positive by both Moody's and S&P.

Capital spending within our Company is primarily for ongoing maintenance and expansion of our existing assets, and if identified, attractive growth opportunities. We have been disciplined in our capital deployment and make growth investments that meet our criteria in terms of strategy, management skills, and identified risks and expected returns. All potential investments are analyzed for their rates of return and cash payback on a risk-adjusted basis. Our total capital expenditures, inclusive of $5 million in contributions to equity method investees, were $355 million for the year ended December 31, 2024 primarily for expansions on Blue Union Gathering, Ohio Utica Gathering, LEAP and Appalachia Gathering. On December 31, 2024, we closed on the Midwest Pipeline Acquisition of three FERC-regulated natural gas transmission pipelines for $1.2 billion. See Note 16, "Acquisitions" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K. We anticipate total capital expenditures, inclusive of contributions to equity method investees, for the year ended December 31, 2025 of approximately $470 million to $550 million.

OFF-BALANCE SHEET ARRANGEMENTS

We are party to off-balance sheet arrangements, which include our equity method investments. See Note 1, "Description of the Business and Basis of Presentation—Principles of Consolidation" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K for further discussion of the nature, purpose and other details of such agreements.

Other off-balance sheet arrangements include the Vector line of credit and our surety bonds, which are discussed in Note 12, "Commitments and Contingencies" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

INDEMNIFICATION OBLIGATIONS

We could have an indemnification obligation to DTE Energy pursuant to the Tax Matters Agreement and the Separation and Distribution Agreement. See Part I, Item 1A. "Risk Factors—Risks Related to the Separation—We agreed to numerous restrictions to preserve the non-recognition treatment of the Distribution, and we could have an indemnification obligation to DTE Energy in accordance with the terms of the Tax Matters Agreement if the Distribution were determined not to qualify for non-recognition treatment for U.S. federal tax purposes." of this Form 10-K for further details.

CRITICAL ACCOUNTING ESTIMATES

The preparation of our Consolidated Financial Statements in conformity with GAAP requires that management apply accounting policies and make estimates and assumptions that affect results of operations and the amounts of assets and liabilities reported in the Consolidated Financial Statements. Management believes that the areas described below require significant judgment in the application of the accounting policy or in making estimates and assumptions in matters that are inherently uncertain and that may change in subsequent periods. See additional discussion of our accounting policies in the Notes to Consolidated Financial Statements in Item 8 of this Form 10-K.

Purchase Accounting

In accordance with business combination accounting guidance, the assets acquired and liabilities assumed in an acquired business are measured at their estimated fair values at the acquisition date. As discussed in the Regulation paragraph below, these acquired FERC-regulated pipelines are accounted for under ASC 980, and thus, the fair value of assets acquired and liabilities assumed subject to these provisions approximate their regulated basis, and therefore no fair value adjustments have been reflected related to these amounts. Customer relationship intangible assets are not subject to rate making and cost recovery provisions, and therefore do include fair value adjustments. Determining the fair value of these items required management's judgment and involved the use of significant estimates and assumptions with respect to the timing and amounts of future cash inflows and outflows, discount rates, market prices and asset lives, among other items. Changes to these estimates and assumptions could result in material changes to the fair value of assets and liabilities as of the acquisition date. For income tax purposes, the transaction is treated as a taxable deemed asset acquisition. Accordingly, the majority of deferred income tax assets and liabilities of the acquired entities are eliminated as the tax bases were increased to fair market value which equals net book value.

See Note 7, "Income Taxes" and Note 16, "Acquisitions" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

Goodwill

We have goodwill that resulted from business combinations. Annually as of October 1st, an impairment test for goodwill is performed which compares the fair value of each reporting unit to its carrying value including goodwill. If the carrying value including goodwill exceeds the fair value of a reporting unit, an impairment loss would be recognized. A goodwill impairment loss is measured as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill.

The October 1, 2024 fair values for the reporting units were calculated using an income approach. The estimated fair value in our annual goodwill impairment analysis utilizes significant assumptions that require judgment by management. One such significant assumption is the weighted average cost of capital (WACC) which is used to discount estimates of projected future results and cash flows to be generated by each reporting unit. The WACC is based on our cost of debt, which includes U.S. industrial bond spreads, and cost of equity, which consists of U.S. Treasury Rates plus an equity risk premium. Another significant assumption is the terminal value that utilizes an assumed long-term growth rate, which incorporates management’s judgment regarding sustainable long-term growth of the reporting units.

Our annual goodwill impairment analysis included a comparison of the estimated fair value of the Company as a whole to our market capitalization. Management also compared the implied market multiple of the estimated fair value of each reporting unit to midstream industry transaction multiples and considered other market indicators to support the appropriateness of the fair value estimates.

51

We performed our annual impairment test as of October 1, 2024 and determined that the estimated fair value of each reporting unit exceeded its carrying value, and no impairment existed. The results of the impairment test are as follows as of the October 1, 2024 valuation date:

[[/GREPCENT_TABLE]]
_________________________________

(a) Percentage by which the estimated fair value of the reporting unit would need to decline to equal its carrying value including goodwill.

(b) Discounted cash flows (DCF) incorporated 2024 (fourth quarter) through 2028 projected cash flows plus a calculated terminal value. We calculated the terminal-year cash flows using an estimated long-term growth rate of 2.5%, discounted at the WACC for each of the reporting units.

In between annual impairment tests, we monitor our estimates and assumptions regarding estimated future cash flows, including the impact of movements in market indicators, and will update the impairment analysis if a triggering event occurs. While we believe the estimates and assumptions in the fair value are reasonable, the actual results may differ from projections. To the extent projected results or cash flows are revised downward, the reporting unit may be required to write down all or a portion of its goodwill, which would adversely impact our earnings. If current expectations of future long-term growth are not met or market factors outside of our control change, such as U.S. Treasury Rates or a decline in midstream industry transaction multiples, this may lead to a goodwill impairment in the future. See Part II, Item 7A., "Quantitative and Qualitative Disclosures About Market Risk", in this Form 10-K for more information on our exposure to market risk.

On December 31, 2024, we completed the Midwest Pipeline Acquisition, which resulted in an addition of $303 million to goodwill under the Pipeline reporting unit. This addition occurred after the completion of our annual impairment test as of October 1, 2024. As part of our year-end procedures, we performed a qualitative assessment of the goodwill balance, including the newly added goodwill from the acquisition, and determined there were no indicators of impairment as of December 31, 2024. See Note 16, "Acquisitions" to the Consolidated Financial Statements under Part II, Item 8 of this Form 10-K.

Assessment of Long-Lived Assets for Impairment

We evaluate the carrying value of long-lived assets, excluding goodwill, when circumstances indicate that the carrying value of those assets may not be recoverable. Conditions that could have an adverse impact on the cash flows and fair value of the long-lived assets are a deteriorating business climate, condition of the asset, or plans to dispose of or abandon the asset before the end of its useful life, which could result from the loss of or reduction in volume from our customers. The review of long-lived assets for impairment requires significant assumptions about operating strategies and estimates of future cash flows, which require assessments of current and projected market conditions and anticipated customer revenues. An impairment evaluation is based on an undiscounted cash flow analysis at the lowest level for which independent cash flows of long-lived assets can be identified from other groups of assets and liabilities. Impairment may occur when the carrying value of the asset exceeds the future undiscounted cash flows. When the undiscounted cash flow analysis indicates a long-lived asset is not recoverable, the amount of the impairment loss is determined by measuring the excess of the long-lived asset over its fair value. An impairment would require us to reduce both the long-lived asset and current period earnings by the amount of the impairment, which would adversely impact our earnings. As part of our ongoing reviews of business operations and associated long-lived assets, we did not identify any indicators of impairment that existed during 2024.

Depreciation and Amortization of Long-Lived Assets

We compute depreciation and amortization based on estimated useful lives. These estimates are based on various factors including condition, manufacturing specifications, technological advances and historical data concerning useful lives of similar assets. Uncertainties that impact these estimates include economic conditions and supply and demand in the area. When assets are put into service, we make estimates with respect to useful lives and salvage values that we believe are reasonable. However, subsequent events could cause us to change our estimates, thus impacting the future calculation of depreciation and amortization. For our regulated assets, depreciation studies to assess the estimated useful lives of the asset are typically conducted as part of rate proceedings or tariff filings, which can result in changes in economic lives. Changes in economic lives, if applicable, are implemented prospectively as of the tariff approved effective date.

Assessment of Equity Method Investments for Impairment

We assess at each balance sheet date whether there is objective evidence that the equity method investment is impaired by completing a quantitative or qualitative analysis of factors impacting the investment. If there is objective evidence of impairment, we determine whether the decline below carrying value is other than temporary. If the decline is determined to be other than temporary, an impairment charge is recorded in earnings with an offsetting reduction to the carrying value of the investment. As part of our ongoing reviews of equity method investment operations, we did not identify any indicators of impairment that existed during 2024.

Regulation

Guardian, Midwestern and Viking are subject to rate regulation and accounting requirements of the FERC. The regulated operations of each of these subsidiaries have rates that are (i) established by independent, third-party regulators, (ii) set at levels that will recover our costs when considering the demand and competition for our services and (iii) collectible from our customers. Accordingly, we follow the accounting for regulated operations as defined in ASC 980, Regulated Operations for these pipelines, which results in differences in the application of GAAP between our regulated and non-regulated businesses. These entities are required to record regulatory assets and liabilities for certain transactions that would have been treated as revenue or expense in non-regulated businesses. Future regulatory changes could result in changes in the amounts of regulatory assets and liabilities or the discontinuance of this accounting treatment for regulatory assets and liabilities for some or all of our regulated businesses. We believe that currently available facts support the continued use of regulatory accounting and that all regulatory assets and liabilities are recoverable or refundable in the current regulatory environment.
